Cacti
- +Free, stable and extremely light on resources
- +Long-established SNMP graphing with a large body of community templates
- +Runs happily on modest hardware in small or isolated environments
- −Graphing-first: alerting requires plugins and is not a core strength
- −Interface and workflow are dated, and development pace is slow
Best for Small or isolated networks needing long-term interface graphing at no cost
Watch out Treat this as a graphing tool rather than a monitoring and alerting platform
Checkmk
- +Rule-based configuration scales far better than per-host definitions
- +Free Raw edition is genuinely capable rather than a limited trial
- +Distributed monitoring is a first-class feature, not an add-on
- −Enterprise features including advanced reporting sit behind paid editions
- −Smaller community than Zabbix or Nagios, so fewer third-party templates
Best for Teams wanting a modern open-core platform that scales without per-device cost
Watch out Confirm which features you need are in Raw before assuming the free edition suffices
